  • DETAILED DESCRIPTION
  • Referring to the drawings, FIG. 1 is a perspective view of a first embodiment of the invention. In this embodiment 10, there is a housing 12 for an electronic component which is formed as a GFCI or ground fault circuit interrupter, having a test button 14, and a reset button 16, a LED indicator light 17, a strap 18, a receptacle interface 19, and electrical contacts 20. Test button 14 and reset button 16 are known in the art and are described in greater detail in U.S. Pat. No. 4,595,894 to Doyle et al issued on Jun. 17, 1986 the disclosure of which is hereby incorporated herein by reference in its entirety. Alternatively, however, the housing and the modular components can be used in a non-GFCI or non fault circuit type device.
  • Electrical contacts 20 include line neutral contacts 22 which are formed as conductors and load neutral contacts 24 which are formed as conductors, as well as line phase contacts (not shown) and load phase contacts (not shown). On the front face of housing 12, is a module release button or element 30. When a module release button is pressed, it is designed to release a module 38 from housing 12 (See FIG. 2). It should be noted that the module release button may be placed anywhere on the device as considerations may require. This button may alternately be located in a place that is inaccessible to the user once installed. Alternatively, the button may be accessible to the user once installed but only with the removal of a wallplate.
  • FIG. 2 is a perspective view of the embodiment shown in FIG. 1 wherein the module is ejected from the housing. In this view, module 38 has at least one power blade 50, wherein when the modular component is inserted into housing 12, the power blade is coupled to at least one of the phase conductors or neutral conductors (See FIG. 3).
  • FIG. 3 is a front view of another embodiment of the invention wherein in this embodiment there is shown a housing 12 a which has at least two receptacles 60 and 70. These receptacles can be in any known shape but are shown here as substantially rectangular shaped. Receptacle 60 has five sides or faces, including a first face 60 a, a second face 60 b, a third face 60 c, a fourth face 60 d, and a fifth face 60 e. First face 60 a has no electrical contacts, second face 60 b does not contain electrical contacts but it does contain a notch or opening 68 which is designed to receive a lock or latch (see FIGS. 5,6 and 7). Third face 60 c includes a contact 66 which is a ground contact for coupling to an associated ground contact 42 (see FIG. 5) on an associated module. Face 60 d also does not contain electrical contacts, however face 60 e which is the back face of this receptacle has two contacts or conductors, a neutral contact 62 in the form of a conductor and a phase contact 64 in the form of a conductor. When a module is inserted into receptacle 60, it is electrically connected to these contacts.
  • Receptacle 70 has five sides or faces, including a first face 70 a, a second face 70 b, a third face 70 c, a fourth face 70 d, and a fifth face 70 e. First face 70 a has no electrical contacts, second face 70 b does not contain electrical contacts but it does contain a notch or opening 78 which is designed to receive a lock or latch (see FIGS. 5,6 and 7). Third face 70 c includes a contact 76 which is a ground contact for coupling to an associated ground contact 42 (see FIG. 5) on an associated module. Face 70 d also does not contain electrical contacts, however face 70 e which is the back face of this receptacle has two contacts, a neutral contact 72 and a phase contact 74. When an associated module 40 is inserted into receptacle 70, it is electrically connected to these contacts.
  • FIG. 4 is a front view of another embodiment of the invention which shows a front view of a double gang modular housing 100 which has four receptacles 60, 61, 70, and 71 for receiving associated modules. These receptacles are the same as the receptacles that were explained in greater detail in FIG. 3. Housing 100 includes a plurality of eject buttons 30, 32, 34, and 36 disposed adjacent to housings 60, 70, 61, and 71 respectively. In addition, this housing also has a reset button 116 and a test button 117. A series of associated LED lights are disposed around reset button 116 and test button 117 including LED indicator lights 120, 122, 124, 126 and 127. LED indicator lights 120, 122, 124 and 126 are designed to indicate whether the associated module has been inserted into associated housings 60, 61, 70 and 71. LED light 127 is a GFCI indicator light which indicates whether the GFCI is in a set or tripped state.
  • FIG. 5 is a front perspective view of an embodiment of a modular component. In this case, modular component 40 can be of any shape but in this embodiment is formed as a block which has six sides. This block has a cross section that is substantially in the form of a rectangle.
  • Modular component 40 includes a housing front face 40 a which has, in this view, a functional component 44 which as shown in this embodiment are receptacle openings 44 a, 44 b and 44 c comprising phase, neutral and ground openings respectively. A second face 40 b includes a locking element 80 which is in the form of a spring loaded locking element (See FIG. 7). In this case, locking element 80 has a hinge which in this embodiment is formed as a natural hinge. Face 40 c which is shown as a top face has a ground contact 42.
  • FIG. 6 is a back perspective view of the embodiment of the modular component shown in FIG. 5. For example, with this design, there is shown a back face 40 d which has phase and neutral contacts 46 and 48, respectively which are formed as metal contacts formed in the housing, wherein modular component 40 can be inserted into an associated receptacle such as any one of receptacles 60, 61, 70, or 71 and be electrically connected to contacts in the housing such as contacts 62, 64, 72, and 74. In this case, for example, when module 40 is inserted into receptacle 60, phase contact 46 contacts the associated phase contact 64, neutral contact 48 contacts the associated neutral contact 62 to form an electrical connection. In addition ground contact 42 contacts associated ground contact 66 to form a ground contact connection.
  • FIG. 7 is a top, cross-sectional view of a first embodiment of a modular component 40 which shows locking element 80 which has a hinge in the form of a natural hinge 81, a body section 82, a spring 86 and a support shaft 88 coupled to body section 82 of locking element 80. Spring 86 is formed so that it is stabilized on locking shaft 88, but disposed inside of a housing section 89. In this case, support shaft 83 locks the spring 86 as well opposite locking shaft 88. This body section also has a recessed region 87 for storing a section of spring 86. When modular element 40 is pressed into an associated receptacle, body section 82 is pressed into housing section 89 to collapse this locking element into the modular element. In this state, spring 86 is thereby compressed and body section 82 is pressed flush against wall 40 b of modular component 40. When this modular component is fully inserted into the receptacle, spring 86 presses locking body section 82 out thereby expanding into opening 89.
  • FIG. 8 shows a top cross-sectional view of another embodiment of a modular component 140 which can also be used to represent the inner workings of modular component 38. In this case, the modular component 140 includes a ground contact 142, and a plurality of spring loaded contacts 145 a and 145 b in the form of a phase contact 145 a and a neutral contact 145 b. Phase contact 145 a and neutral contact 145 b are each formed as a plunger or power blade which provides power to the functional part of the modular component. Contacts 145 a and 145 b include springs 142 a, and 142 b which are coupled to shafts 146 a and 146 b. These spring loaded contacts or plunger 145 a and 145 b are disposed inside housings 144 a and 144 b. Shafts 146 a and 146 b are made from a conductive material such as metal and extend inside of housing 141 a and 141 b and are coupled to associated face terminals, or to an integrated electronic component in housing 141. For example, shafts 146 a and 146 b are housed inside of associated contact shafts 147 a and 147 b which are in communication with electrical components disposed inside of housing 141.
  • For example, there are brush contacts 149 a and 149 b which are coupled to shafts 146 a and 146 b respectively and are in contact with plate contacts 151 a and 151 b respectively. Essentially, these spring loaded contacts 145 a and 145 b are compressible so that modular component 140 can be inserted inside of the associated receptacle 60 inside of housing 12. These power blades 145 a and 145 b can have respective associated key sections 145 a or 145 b which mate with a corresponding opening.
  • FIG. 9A is a top view of an alternative embodiment of housing 200 showing an ejection or release mechanism for ejecting a modular component such as modular component 40 from a housing or receptacle 60 or 200. For example, in this embodiment, there is a receptacle or housing 200 which has a receptacle region 201 which includes a release or ejection device or mechanism 210. Release or ejection device or mechanism 210 includes a base 211 which is coupled to a spring 214. Spring 214 is substantially disposed inside of housing 212 which is used to guide spring 214 and a plunger 216. Plunger 216 has a locking element or mechanism 213 coupled to it, and which is formed similar to a snap lock such as snap lock 80. This snap lock 213 selectively locks plunger 216 in place.
  • Housing 200 has an opening wherein this opening is adapted to receive an actuator arm 220 which is essentially part of the release mechanism which moves axially along a shaft region formed in housing 200. Actuator arm 220 is acted on by pressing arm 230 which has a ramp section 234 which is used to drive actuator arm 220 in an axial manner as an axial to axial translation Pressing arm or plunger 230 forms at a first end an eject button such as eject button 30 shown in FIG. 2. At the opposite end of pressing arm 230 is a spring 232 which is coupled to a base 233. When a user presses on pressing arm 230 it drives ramp 234 against actuator arm 220 causing an axial movement of actuator arm 220 against snap lock 213, thereby releasing plunger 216 causing spring 214 to drive plunger 216 causing plunger 216 to release and press against an associated module 40, driving module 40 outside of housing 201.
  • In addition, inside of housing 200 are contacts in the form of electrical contacts 240 and 242. For example, contact 240 is a neutral electrical contact which is in contact with an associated neutral line, while contact 242 is a phase contact in contact with an associated phase line.
  • Thus, when any one of the modules including modules 38, 40 and 140 are inserted into receptacle 201, the contacts such as blade 50 or module 38, contacts 46 and 48 on module 40, or key contacts 148 a and 148 b on module 140 contact these contacts to form an electrical connection with an electrical device inside of either module 40 or module 140. Thus, with this design, each of the modules is protected or controlled by an associated fault circuit such as a GFCI. Thus, even if the design is associated with a double gang enclosure, a single fault circuit can control four modules in the associated housing.
  • FIG. 9C shows another embodiment of a receptacle such as receptacle 60, which has openings 340, or 342 which are adapted to receive associated keys 148 a or 148 b, wherein these keys are used to lock the modular component into the housing. In addition, there is a plunger or eject shaft 311 similar to plunger 216 which is used to eject a modular component from a housing. The substantially rectangular shapes of openings 340 and 342 are shown to represent unique openings which are adapted to receive associated keys.
  • In all, multiple different kinds of functional elements can be disposed inside of these modules. Some of these functional elements include: outlets, switches, timers, occupancy sensors, clocks, dimmers, tamper resistant switches, nightlights, air fresheners, blanks for unused ports, radios and carbon monoxide detectors. Other types of electronic functional components can be used as well.
  • FIG. 10 shows an additional version which has a front cover 351 which is coupled to a front face of housing 12, 12 a or 100 which is designed to cover over the eject button 30, or 230 in a covering region 353 when cover 351 is coupled to housing 12, 12 a or 100. Thus, with this design, once the modules are inserted into their respective receptacles, the eject button is covered over to protect these modules from being unnecessarily ejected. In addition in this embodiment, the cover 351 can be coupled to housing 12, 12 a, or 100 in any manner. With this view, the cover is coupled to the associated housing via a screw which in this embodiment is in the form of a counter sunk screw. In this embodiment the counter sunk screw is a tamper resistant screw, however other alternative means for coupling the cover to the housing can be used as well.
  • Accordingly, while only a few embodiments of the present invention have been shown and described, it is obvious that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
